Design Works Interview

Miyazaki: For the warrior we wanted to move away from the traditional soldier class seen in Demon's Souls and instead aim for something more like an adventurer, we used the relatively simple image words of leather armour with metal plating, and I suppose, a little of Parn from Record of Lodoss War.
I assumed that players would spend a significant portion of the game using this armour so we actually paid special attention to the back as it's the part the players will be looking at the majority of the time. It's the same with armoured core, we have to ensure that each and every camera shows the player some little detail or point of interest. We tried a number of different ideas but in the end we actually settled on something very close to the initial idea. The final design walks that line between warrior and adventurer so I'm really happy with it.Nakamura: When I started work on these four designs I decided that I didn't want to just create a standard set of armour and swap parts around, instead I aimed to create something that while not traditional, looks like it could exist. Designs which felt like they were from another world but that were entirely plausible. That's what I was really strived for.

Theories

Roman Legionary Influence

The armor of the Warrior resembles a roman legionary, specially in the shoulders and the helm, which is specifically called "Standard Helm". Maybe it serves as a hint of the common rank of this soldier.
